RMS Current Measurement Accuracy
This test verifies the measurement accuracy of the rms current readback.
Step Action Normal Result
1 Turn off the UUT and connect the appropriate load resistor, current
shunt and DMM as shown above.
2 Turn on the UUT. Program the output to RANGE 155 V,VOLT 80, FREQ
60.
Output Voltage at 80 Vrms, CV annunciator on,
output current near:
5 A for AC6801B
10 A for AC6802B
20 A for AC6803B
40 A for AC6804B
3 Record DMM reading and calculate rms current Readings are within specified current limits.
4 Program output to RANGE 155 V,VOLT 80, FREQ 500. Output Voltage at 80 Vrms, CV annunciator on,
output current near:
5 A for AC6801B
10 A for AC6802B
20 A for AC6803B
40 A for AC6804B
5 Record DMM reading and calculate rms current. Readings are within specified current limits.
6 Turn on the UUT. Program the output to RANGE 310 V,VOLT 160, FREQ
60.
Output Voltage at 160 Vrms, CV annunciator on,
output current near:
2.5 A for AC6801B
5 A for AC6802B
10 A for AC6803B
20 A for AC6804B
7 Record DMM reading and calculate rms current Readings are within specified current limits.
8 Turn on the UUT. Program the output to RANGE 310 V,VOLT 160, FREQ
500.
Output Voltage at 160 Vrms, CV annunciator on,
output current near:
2.5 A for AC6801B
5 A for AC6802B
10 A for AC6803B
